NOTES:
Ranking (best → worst candidate for IPv6 LAN testing):
- Re-Volt (RVGL) — Best bet. It's an actively maintained open-source port, so the networking code is inspectable/patchable, and modern open-source projects are far more likely to use protocol-agnostic sockets (
getaddrinfo, dual-stack) than 2000s-era closed engines. If IPv6 doesn't work out of the box, you can actually check or modify the source. - Assetto Corsa — Explicit direct-IP-entry server model makes it the easiest to test (you control exactly what address you type), but its custom Kunos netcode dates to ~2014 and was built IPv4-first; no confirmation of IPv6 socket support.
- Wreckfest — Modern-ish engine (Bugbear, released 2018) with in-game LAN hosting, so somewhat more likely to use current-gen networking libraries than the older titles, but again unconfirmed and likely still IPv4-oriented broadcast/direct connect.
- Trackmania Nations Forever / Turbo — LAN tab typically uses direct IP too, but TMNF's netcode is ~2008-era Nadeo code; low odds of IPv6 support, though at least testable via explicit IP field.
- NFS Underground 2 / Most Wanted (2005) — Lowest odds by far. Mid-2000s console-ported netcode almost certainly hardcodes IPv4 (many even used raw IPX-derived or DirectPlay-based discovery), and there's no active maintenance to have added IPv6 since.
- Mobile titles (Rush Rally 3, Beach Buggy Racing, Mini Motor Racing) — Ranked last for your specific purpose, not because they don't work over LAN, but because they abstract the network layer through OS-level local multiplayer APIs (Wi-Fi Direct / hotspot discovery). You have little to no visibility or control over whether the underlying transport picks IPv4 or IPv6, making them poor choices for isolating and verifying IPv6 specifically.
Top PC Racing Games with True IPv4 LAN Support
If you are playing on a computer network, these titles let you host a direct local server:
Assetto Corsa: The ultimate gold standard for realistic track physics. While the newer Competizione focuses heavily on matchmaking, the original Assetto Corsa has a built-in local server manager. You can spin up a local server instance on a PC, and anyone on the same network can join by typing in the local IP address.
Trackmania Nations Forever / Trackmania Turbo: If you want hyper-fast, arcade time-attack racing, this series is a legendary LAN staple. You can create a local network profile and host rooms for dozens of players simultaneously.
Wreckfest: A chaotic demolition derby and racing simulator. It fully supports local network hosting from the in-game menus, allowing you to fill a grid with your friends and AI bots to smash each other up.
Re-Volt (RVGL Open-Source Port): If you remember the classic 1999 RC car racer Re-Volt, a community project called RVGL rewritten it to run flawlessly on modern Windows, Linux, and Steam Deck setups. It features a robust, low-latency native LAN mode.
Need for Speed: Underground 2 & Most Wanted (2005): If you are willing to look into older physical copies or abandonware, the mid-2000s Need for Speed titles are famous for having native, flawless plug-and-play offline LAN lobbies right out of the box. [1, 2, 3, 4]
Top Mobile Racing Games (Offline Local Wi-Fi)
If you want to play on phones or tablets by having one person turn on their mobile hotspot (without mobile data/internet) and having others join it, these games work natively: [1, 2]
Rush Rally 3 / Rush Rally Origins: Highly praised as the absolute best realistic rally simulators on mobile. They natively support local multiplayer over a shared Wi-Fi network without requiring an internet connection.
Beach Buggy Racing 1 & 2: An action-packed off-road kart racer similar to Mario Kart. You can easily host local Wi-Fi split lobbies directly from the app interface.
Mini Motor Racing: An intense, top-down isometric combat racer that lets up to four players battle each other using local network connections. [1, 2, 3, 4, 5]
